The invention relates to a device particularly adapted for molding frozen confections. Devices are known wherein a mold with multiple cavities is filled with a semi-solid ice cream 5 mix with a superposed carrier having a pin extending into each cavity so that the Ycongealed confection adheres to the pins. After the bond between the confections and the mold `wall is broken, the carrier is removed and the confections are then dipped into a chocolate bath, if

desired, and subsequently a stripper on the carrier, when actuated, breaks the lbond between the confections and the appertaining pins;

In making molded confections in'quantities, it

tions in dozens, but a device for producing two dozens at one time has been found most satisfactory to the industry as meeting the' requirements of commercial production andwear and tear on the device.

In the known apparatus the confections have been stripped from the carrier in a single operation, causing thereby thedevice toA be subjected to great strain and to become Warped andbent after short use. v

It, therefore, constitutes the principalv object of the invention to provide means for successively breaking the bond betweenY the confection and pins so that a greatly reduced force is applied during the stripping action.

A further object aims at providing a 'sectionalized stripper device, each section being actuated in timed relation so that successive stripping is provided, necessitating only a fraction of the force as compared with simultaneous stripping of all of the confection at one time.

It is a. still further object to mount the rods or pins movable on the carrier, and actuating said rods in a predetermined order.

With these and other equally important objects in View, which will become apparent from a perusal of the invention, the latter comprises the means described in the following specification, particularly pointed out in the 'claims forming a part thereof, and illustrated inthe accompanying drawings, in which:

Fig. 1 is a top plan View of the device constructed in accordance with my invention.

has been found to be preferable to mold confecp "Fig-V8 is a view similar to Fig. 7 with the stripper plate in nal position, and Fig'. 9 is a fragmentary horizontal section on the 'line 9-9 vof Fig. 8.

Referring to the several views in the drawings, i-

themold lgenerally designated by I0 forms a box like structure of rectangular cross section having end walls II and I2 and side walls I3 and I4. Handles I5 are riveted or otherwise secured to the end walls for facilitating lifting or lowering of the mold, suchjas becomes necessary'in connection with freezing in a brine'tank.

'The bottom I6 is provided with openings I'I,

ither'ebeing 'six rows of four openings in eachr Y I'he containers are tapered toward the bottom and at the lower end are beveled as at 20 andY 2 I Y (Fig. 4), so that the confections 60, when removed from the containers, terminate at the bottom vin a sharp line. Any Vothershape may be selected.'

` Cooperating with the mold box I0 isa carrier which is adapted to be receivedY in the box and held in position so that pins or rods, later to be described, project into the containersfor having the confections congeal on said rods. The carrier generally designated by 22 comprises a rectangular plate 23 which, throughout its perimeter,V has4 an upstanding flange 24 and is also provided with large openings 25 to afford Vinspection of the freezing process occurring in the containers I8.

The carrier plate has triangular upstanding `bearing plates 26 near each end, from each of :which extend laterally a horizontal pin or stud "2l, 'adapted tocontact with the upper edge of the boxfIU to limit the extent to which the carrier 'mail be loweredinto the mold.'

l Brace rods 28r connect the bearing plates at eachend of the carrier.

'Ihe pin framev is made up` in sections one of whichlcom'prises two longitudinal angle iro-ns 29, 30 which are connected at the ends by a cross bar 3|, which is provided with spaced slots to receive downwardly projecting pins or rods 32 of a U member 33 riveted to the cross bar or otherwise secured thereto.

At the center of the frame, a cross bar 34 is connected to the angle irons 29, 30, which are slightly shorter than the length of the carrier plate 22.

Inwardly of the angle irons, and parallel "fao thereto, are longitudinal bars 35, 36, which extend slightly beyond the outer end of the bearing plates 26, and are adapted to be limited in the upward movement by stops 31 formed asintegral flanges of the bearing plates 26.

The bars 35 and 36 are connected by cross members 38, 39, one at each side of the cross bar 34 and secured to the bars 35, 36 by rivets 46, and each member is provided with a pair of U-members 33 in aligned relation, so that the pins 32 extend into the container I8, as will be readily seen by reference to Fig. 2, the plate 22 having slots 25a for the passage of the pins (Fig. 9).

The longitudinal bars 35, 36, together with the cross members 38, 39, constitute a frame for the eight center pins 32.

The cross members 38, 39 are formed with overhanging horizontal flanges 4| for a purpose hereinafter described.

Additional cross members 42, 43, constituting frames to which U-members 33, are secured with downwardly projecting pins 32, are bent at right angles at the ends and extend into horizontal flanges 44 (Fig. 5) overlying the bars 35, 36.

To the angle ironsare secured vertical plates 45 which are provided with outwardly extending horizontal flanges 46 overlying the flanges 4|. The flanges 44 are in a plane midway between the flanges 4| and 46.

To the bearing plates 26 is pivotally secured, as at 48, a bell crank lever 41 which, at the upper end, is connected to the companion lever by a handle bar 49.

The lever 41 has wound around its pivot a coiled spring 50, anchored at one end to the bearing plate 26, as at 5|, and engaging the lever 41 so that the lower leg 52 is in downward position.

Any other spring meansmay be employed, if desired.

In use, the parts are originally in the position shown in Fig. 2. After the bond between the confections and the mold walls are broken, the carrier is lifted by the handles 28 and, if desired, the confections adhering to the pins 32 are dipped in a chocolate bath. Then the levers 41 are turned outwardly against the action of the springs 5U, by drawing handles 28 and 49 toward each other, whereby the lever leg 52 engages the flanges 4|, causing a lifting of the bars 38, 39, together with the longitudinal bars 35, 36, whereby eight confections are elevated. The latter, in their upward movement, engage the flanges 44, causing lifting of the cross bars 42, 43 so that eight additional` confections are elevated.

In the continued movement of the levers 41, the flanges 4| engage the iianges 46, whereby the angle irons 29, 30 and the cross bars 3| are lifted, causing the elevation of the remaining eight confections.

The timed elevating of the confections, as shown, causes them in series of eight to be pressed against plate 23, thereby successively breaking the bond between the confections and the pins.

The c ross bar 34 travels in a bail member 53, which is secured `to the plate 23 and is provided with abutments 54. The cross bar 34, due to the spring action of the bail member 53, passes the abutments 54 in its upward movement, and is held against descent, as shown in Fig. 8.

Continued upward movement of the stripper is prevented by engagement of the bars 35, 36 with the stops 31 of the bearing plates as previously mentioned.

To return the stripper to normal position, downward pressure is exerted preferably on the cross bars 3| to force the cross bar 34'past the abutments 54. Likewise abutments 54a prevent movement in reverse direction if device is inverted'. Any spring lock may be used in lieu of bail 53.'

It Will readily be understood that the stripping is obtained in three stages involving, first, the center eight pins, then the adjacent eight, and nally, the remaining eight pins on the bars 3|. Accordingly, one third of the pressure is applied to removethe confection, as compared with the pressure necessary Where rall of the confections are stripped simultaneously.

'Ihe removal of the confections in stages, at timed intervals, will make the stripping action more accurate and reliable and, in addition, the wear and tear on the device will be greatly lessened, so as to prolong the life thereof.

While the drawings show a preferred embodiment of the invention, numerous changes and alterations may be made without departing from the spirit thereof.

I, therefore, do not limit myself to details of construction and arrangement, as shown, but claim my invention as broadly as the state of the art permits.
